Patented Nov. 15, 1938 UNITED STATES PATENT OFFICE 16 Claims.

My invention relates generally to an arrow head construction and moreparticularly to one for hunting wild game.

Briefly described, my invention comprises an impact or cutting plate anda specially designed slotted tip of bullet shape for receiving theplate, together with means for rigidly locking them together.

One of the primary advantages of my invention lies in the simplicity andelliciency of the completed article, the arrow to which it is attachedbeing perfectly balanced whereby it speeds, without lateral vibration,along its path.

Another advantage lies in the simplicity of the parts, these beingeasily and quickly manufactured. Furthermore, onlytwo parts are neededand this construction keeps down the cost of production.

Yet another advantage lies in the manner of fastening the two partstogether, the fastening operation being quickly and expedientlyaccomplished. Also, the means for holding the two parts together is ofsuch shape and has suflicient area to perform this function properly. Inother words the two parts are positioned, with ation to one another,exactly as desired and are rigidly locked in this symmetrical and exactrelationship.

Other advantages will be understood by archers and those skilled in thisart as the description proceeds.

In the drawing:

Fig. 1 is a side view of the tip or shell, this being fastened upon theforward end of the arrow shaft.

Fig. 2 is a View at right angles to Fig. 1.

Fig. 3 is a sectional view taken along the line 3-3 of Fig. 2.

Fig. 4 is a side View of the impact plate.

Fig. 5 is an edge view of the impact plate.

Fig. 6 shows my completed unit ready to be forced by twisting andtranslation onto the front end of an arrow shaft.

Fig. 7 is a rear view of the assembled head.

Fig. 8 is a side view of a modified form of impact plate.

Fig. 9 is a detail view of the edge construction of the impact plate,this view being taken along the lines 9-9 of Figs. 6 and 8.

Similar numerals refer to similar parts throughout the several views.

Referring to Figs. 1, 2 and 3, numeral ID indicates the shell or pointwhich has a cylindrical part II and a tapered part I2. The part [2merges to a complete closure and the other end of the shell is open toreceive the arrow shaft. The tip of the shell is slotted or notchedaxially The impact plate 20, preferably formed of a plate of Swedishsteel of uniform thickness, has its front end 2i pointed at an angleless than 30 degrees. The sides of the plate, 22 and 23, meet the rearfaces 24 and 25, respectively, at angles of approximately degrees. Thiscauses the rear faces to aid rather than to hinder during The plate 26is at 29, this curvature approaching but being somethe nose or front ofthe point or shell. See Fig. 6, referring to the dotted lines. Shoulders39, see Fig. 4, extend as shown and serve to prevent rearward the shellbeyond sidewise play therebetween.

The two parts may be assembled by spring actual bending of the shellafter which the shell is straightened. There-- upon the two parts are inthe position shown in Fig. 6 and the wooden shaft 3! is now twisted andmoved into the assembled unit, the lugs 2'! slot l3 and then a quickblow given to the protected point of the plate thus causing the surfaces43 and 44 to slide along the outer surface of the shell to above andthen into the openings 14. Thus the elements are joined together.

However, the preferred form of assembly is as previously explained, thatis, bending the rear portions of the shell adjacent the small openingsl4 toward one another until the plate 40 may be slid thereover. It isunderstood that the shell is bent no more than is absolutely necessary.My idea of rounding the lugs at their tips or shaping them as shownfacilitates the assembly.

As shown in Fig. 8 the small lugs are longitudinally spaced and are ofsufficient length to extend through the shell. During assembly of thecompleted head upon its wooden shaft a rotary movement is employedwhereby the small lugs cut into the wooden shaft and cut a helicalgroove therein, the pitch of this thread being twice the distance 45.See Fig. 8. The wooden shaft is shown at 3| in Fig, 6. Thus the metalhead is securely attached to the wooden shaft.

Fig. 9 illustrates the edge construction of the plate. It is to be notedthat these edges are beveled and then the medial surface of the beveledportion is cut away in a curved surface as shown. I have discovered thatthis makes the withdrawal of the arrow materially easier.

In conclusion, my article is lessened in weight by cutting away themetal of the plate at 29 in the one form and at 46 in the other form,thus making a better device.

My construction provides for secure attachment both between the twometal parts of the head and also between the completed head and theshaft. Even without the twisting assembly the parts are retained by theresiliency of the wooden shaft and its tendency to spring back intoshape.

Having thus revealed this invention, I claim as new and desire to securethe following combinations and elements, or equivalents thereof, byLetters Patent of the United States.

I claim:

1. A broadhead arrow tip of bullet shape having a plate fastened theretoand extending forwardly therefrom to form an acute angle point, saidplate extending alongside of the tip to reinforce the same and saidplate having means for biting into the wooden shaft which may bereceived within the said tip.

2. In combination, a flat plate pointed at one end and medially cut awayat its other end, a cylindrical element with a closed end, said endbeing slotted, said slot receiving the cut away portion of the fiatplate whereby the same and the said element are nested together, thedegree of nesting being such that the closed end of the element isbetween the ends of the plate and the end of the plate having the cutaway portion is between the ends of the said cylindrical element.

3. An arrow head for hunting wild game comprising a metal shell havingone end pointed and the other end open, said closed or pointed end beingslotted rearwardly, a metal plate formed of spring steel having apointed front end and being symmetrically cut away to enter said slotand to extend rearwardly along both sides of the said shell, said shellhaving a slot in alinement with said metal plate and means on the plateextending into the said slot.

4. An arrow head as set forth in claim 3 in which the said means extendsthrough the shell some little distance for the purpose described.

5. An arrow head as set forth in claim 3 in which the shell hasoppositely disposed slots and the plate has means extendingtherethrough.

6. An arrow head as set forth in claim 3 in which the metal plate isshouldered to contact the rear of the slot in the. metal shell.

'7. An arrow head of the class described comprising a bullet shapedshell slotted rearwardly from its nose a short distance, an impact platehaving a thickness equal to the width of the slot, said plate beingslidably received within the said slot and cooperatively associatedmeans between the rear of said shell and the plate for preventingmovement therebetween.

8. An arrow head as recited in claim 7 in which the said plate hasshouldered portions abutting against the rear of said slot.

9. A hunting arrow head comprising a pointed plate, a shell of bulletshape having its nose symmetrically located on opposite sides of theplate and intermediate along its length, the rear of the plateterminating prior to the rear of the bullet shaped shell, the rear edgesof the said plate extending rearwardly and inwardly for the purposedescribed.

10. A hunting arrow as set forth in claim 9 in which the angles at therear of the plate are greater than right angles.

11. An arrow head as set forth in claim 9 in which the angles at therear of the plate are each approximately 12. In combination, a metalarrow tip having its nose slotted rearwardly, said tip being hollow, aplate received in said slot, said plate being pointed, said plate beingcut away so as to not extend interiorly across the tip, and means forfastening the rear of the plate and the tip together.

13. An arrow tip comprising two elements, one element being of bulletshape and the other being flat, said bullet shaped element being slottedmedially from its tapered end, said flat element being received thereinand means for fastening the flat element to the other element at adistance from the said slot.

14. An arrow tip as set forth in claim 13 in which the bullet shapedelement is hollow and the fiat element is cut away so as to not extendthrough the said slot into the interior of the hollow element.

15. An arrow head of the class described comprising, a flat metal platehaving its side edges acutely positioned to form a point, an elongatedmember having an axial recess therein to receive the shaft of an arrow,said shaft being entered from one end of the elongated member, the otherend of said elongated member being slotted, said plate opposite itspoint being entered into said slot and means for holding the plate andthe member together.

16. An arrow head as set forth in claim 15 in which said holding meansincludes a projection extending from the plate through the elongatedmember into the said axial recess, said holding means being barbed toprevent accidental withdrawal of the arrow shaft.
